(B) Lateral radiograph of the ankle of the same patient of (A). Regarding the length of the fibula, the articular portion reaches further in distal direction in comparison to the medial malleolus. (A) Ankle anteroposterior (AP) mortise view of a healthy young male showing the configuration between distal tibia, distal fibula and talus. The contact zone between tibia and fibula is covered by a thin layer of cartilage forming the syndesmotic recess. Likewise, the anterior (Le Fort-Wagstaffe tubercle) and posterior tubercle of the fibula form a convex triangle. The incisura tibialis is formed by the anterior (Chaput’s tubercle) and posterior tubercle of the tibia ( Fig. The concave-shaped incisura tibialis matches the convex shape of the fibula ( Fig. 4– 6 Besides the connection between tibia and talus, there exists a close interaction between tibia and fibula. Considering the bone mineral density of the tibia, the articular site shows a higher density in comparison to the metaphysis. Looking at the coronal plane, the tibia shows a slight slope from medial to lateral and is concave-shaped in the sagittal plane ( Fig. 2, 3įrom the tibia, the facies articularis medialis (pilon) and the facies articularis inferior are connected to the talus. Tibia, fibula and talus are interconnected through collateral ligaments and the syndesmotic ligament complex. 1 The talocrural (TC) joint is formed by three bones and a complex ligamentous apparatus. The human ankle joint complex can be divided in a talocrural, a talocalcaneonavicular and a subtalar part.
